I will have to get back to you on this. I've already installed a newer
libocct from source, as well as built KiCad 8 from source (my long-term
plan anyway, as I maintain my own fork) and got around the problem. So
my libTKernel won't have the same checksum as what was originally installed.
To keep chasing this, though, I'll spin up a VM and see if I can
recreate the issue in order to answer your questions. Kindly give me a
few days, as my schedule is quite packed this month thanks to various
organizations' holiday activities.
Cheers,
-Brian

That symbol is provided by libTKernel.so.7 from libocct-foundation-7.6,
which is installed on your system, according to the dependency list.
Can you check that the dynamic linker selects the correct library?
$ ldd /usr/bin/_pcbnew.kiface | grep TKernel
libTKernel.so.7 => /lib/x86_64-linux-gnu/libTKernel.so.7
(0x00007f2c2c818000)
The library should be taken from either /lib or /usr/lib. For me, the
checksum is
$ sha256sum /lib/x86_64-linux-gnu/libTKernel.so.7
8ff26e8c80b4910d38f2ebb9dc581d68d285298fd0351ab77f30c609e956b04b
/lib/x86_64-linux-gnu/libTKernel.so.7
and the symbol is indeed provided from there.
$ nm -D /lib/x86_64-linux-gnu/libTKernel.so.7 | grep
_ZNK15Message_Printer4SendERK26TCollection_ExtendedString15Message_Gravity
00000000000e4a70 T
